Title: Optical transmitter
Inventor: MURAKAMI MAKOTO
IPC: H04B10/588
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To attain long range transmission in an optical communication system by changing the polarization state of an optical signal made incident in an optical fiber at a higher speed than that equivalent to a Brillouin scattering response time so as to improve input optical power due to the Brillouin scattering. SOLUTION: A polarization state of an optical signal is changed at a faster speed than that equivalent to a Brillouin scattering response time. In this case, a steady light outputted from a light source 1 is inputted to an intensity modulator 3, in which the light is intensity-modulated by a data signal source 4. The optical signal is given to a polarized wave modulator 11, in which the signal is subject to polarized wave modulation by an electric signal source 12 driving the polarized wave modulator 11 and the modulated signal is sent to an transmission line 5. Furthermore, even when the intensity modulator 3 is replaced with a frequency modulator or a phase modulator, the modulation state is similar. Or the direct modulation system modulating a bias of the light source 1 may be employed.  Or when the intensity modulator 3 without any polarization dependency is in use, the arrangement of the polarized wave modulator 11 and the intensity modulator 3 may be reversed.

IPC: G06F17/24
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To print by easily adding characters partly written horizontally in a character row of vertical writing. SOLUTION: When a vertical printing is set, a setting means for partly printing horizontally is provided and a size of width is aligned and printed horizontally. For printing an optional character row 'CD' in a character row data 'ABCDE' stored as a text data of vertical writing in a way of horizontal partial writing, a 'horizontal composition' key of a key input section is operated so as to designate a range. Then, a horizontal composition flag H is added and stored in a character data of a horizontal composition designating range. When printing operation is started, from the number of continuous characters of the horizontal composition flag H added to the character data of individual text data, a range of partial horizontal printing is determined.  A total length L of the horizontal writing character font at the pertinent part is contracted so as to be aligned to a font width W of other vertical writing character, expanded into a print buffer, and printed as a vertical writing text data which contains the partial horizontal writing characters.

Abstract: PROBLEM TO BE SOLVED: To prevent any drop in the extent of turning performance, attributable to inequality of tension acting on a belt cord, from occurring by varying the modulus of elasticity in the belt cord of a belting ply in a systematic manner. SOLUTION: A belting ply 10 is arranged with a high elastic belt cord C1 of the largest tensile elasticity E1 in the one side edge, and a low elastic belt cord Cn of the smallest tensile elasticity En in the ether side edge the other way, respectively.

Abstract: PURPOSE:To enhance acoustic insulation, effect, by mounting one of plural steel plates for antivibration, which is longer than the other steel plates, to a reinforcing stay. CONSTITUTION:An antivibration steel plate 13 mounted between reinforcing stays 7 is welded uniformly by putting attenuating material 4 between two steel plates 2, 3. One steel plate 3 is directly welded to the reinforcing stays 7 in its extension 3a by extending outside the other steel plate 2. Magnetic distortion vibration generated at an iron core 9 is transmitted to a side plate 6. However, majority of noise generated at portions where no reinforcing stay 7 is mounted is isolated by an acoustic insulator 13. On the other hand, the vibration from reinforcing stays 7 can be transmitted by controlling the vibrating transmission from reinforcing stays 7 to the acoustic insulator 13, as the steel plate 3 welded directly has characteristics of a plate spring.
